Description

Stndon sheath, fascia release device

Technical field

The utility model relates to the field of medical instrument technology, and in particular to a kind of stndon sheath, fascia release device.

Background technique

Currently, need to be cut using small needle knife when treating de Quervain's disease, fascitis or by the various symptoms of its initiation The stndon sheath or fascia of lesion, with the stndon sheath or fascia of lesion of loosening；The blade of traditional needle knife is relatively narrow, and when operation need to mention slotting repeatedly And adjustment direction is cut and (scatterplot of cutting is formed line), damage is larger, and cutting does not form straight line, and loosens and is not thorough, shadow Ring curative effect.

In addition, being easy to make lower-hierarchy (such as tendon, muscle and nerve) when entering tissue using traditional small needle knife At damage, it is unfavorable for the health of patient.

Therefore, how to design a is this field to lower-hierarchy damage small and thorough stndon sheath of loosening, fascia release device Technical staff's technical problem urgently to be resolved.

Utility model content

For the defects in the prior art, the utility model provides a kind of stndon sheath, fascia release device, with the stndon sheath to lesion Or fascia plays thorough dissolution, and lower-hierarchy can be protected from damage.

In order to solve the above technical problems, the stndon sheath of the utility model, fascia release device, including bottom plate and needle knife, the bottom The top of plate penetrates through be provided with holding tank along its length, and the two sidewalls bottom of the holding tank offers guide groove；It is described Needle knife includes blade and the cutter head that is connected on front side of the blade, and the two sides of the cutter head are provided with guide post, the guide post and institute Guide groove is stated to be slidably connected, and the needle knife can the guide post be axially away from the bottom plate direction rotate；The knife Head includes the blade positioned at the blunt portion of front side and positioned at rear side.

The stndon sheath, fascia release device of the utility model cure mainly de Quervain's disease, fascitis or the various diseases caused by it Shape carries out conventional skin degerming first, skin, stndon sheath (or fascia) is broken with knife, by bottom plate and needle knife in treatment Then component adjusts angle of the blade relative to bottom plate, needle knife of pulling back, after being located at cutter head below opening insertion stndon sheath or fascia The blade of side can then cut the stndon sheath or fascia of lesion, the stndon sheath or fascia of the lesion that achievees the effect that loosen；With traditional small needle Knife is compared, and in the stndon sheath or fascia for lesion of loosening, bottom plate is located at stndon sheath or fascia for the stndon sheath of the utility model, fascia release device Bottom, needle knife and lower-hierarchy (such as tendon, muscle, nerve and blood vessel) separated, to cut lesion in needle knife When stndon sheath or fascia, bottom plate can protect lower-hierarchy from damage, moreover, because by guide post and leading between bottom plate and needle knife It is slidably connected to slot, then needle knife can cut pathological tissues progress during pulling back to fast and stable linearly, reduce Damage, achievees the purpose that thoroughly to loosen；Further, since the front side of cutter head is blunt portion, avoids and damage is generated to tissue when entering Wound.

Preferably, the front end of the bottom plate is rounded down along the two sides of its width direction, and the needle knife is from the front end of bottom plate It slides to the back-end, it is obtuse design then when entering, on front side of bottom plate and needle knife that the front end two sides of bottom plate, which are equipped with fillet, into One step prevents the front end of bottom plate and needle knife to generate damage to tissue when entering.

Preferably, the cutter head is a quarter circle laminated structure, including an arc-shaped side and two straight lines are described Arc-shaped side is located at the front end of the needle knife, and one of straight line is connect with the blade, another straight line and the blade Vertically；At the arc-shaped side of the cutter head with a thickness of 1mm, form the blunt portion, the straight line vertical with blade forms institute State blade.Blade and blade in vertical state, then when needle knife is pulled back, cutting of the blade to pathological tissues of being more convenient for.

Preferably, the blade is provided with knife handle far from one end of the cutter head, in order to medical staff hold knife handle into Row operation.

Preferably, the bottom plate and needle knife are all made of metal and are made, in order to bottom plate and needle knife carry out high temperature, high pressure disappears Poison.

Preferably, the length of the needle knife is greater than the length of the bottom plate, in order to medical staff's operation.
